The tape was given to me by Richard, VK7RZ and came from Phil Andrews.
Phil, who died a few years ago, was the Curator of Zoology and Applied
Science at the Tasmanian Museum and Art Gallery.
The creator of this particular tape with added identifications is unknown,
but it is apparently based on recreations of spark signals made for members
of the Antique Wireless Association,
possibly by W6AX for an AWA convention about 1965.
73, Ric, VK7RO
